cadmium induced histopathology in the olfactory epithelium of a snakehead fish, channa punctatus (bloch)
histopathology on the olfactory organ of a snakehead fish, channa punctatus (bloch, 1793) were assessed after exposing the fish to 2.5 mg/l and 5mg/l of cdcl 2 for 15 days, 30 days and 45 days. cellular organization of the epithelium was affected severely with degeneration of sensory and supporting cells and hyperplasia of basal cells and mucous cells. mucous cell proliferation indicates the up...
متن کاملBiopsies of human olfactory epithelium.
It has been shown that olfactory epithelium can be safely biopsied from the living, intact human being. Observations of the ultrastructure of this epithelium shows changes that can then be correlated with the etiology and degree of olfactory loss, allowing a greater understanding of both normal transduction and of the pathology of dysfunction. Examples of the common forms of olfactory dysfuncti...
متن کاملHistological and ultrastructural studies of the olfactory epithelium of spotted butter fish Scatophagus argus (Linnaeus).
The olfactory epithelium of Scatophagus argus (Linnaeus) was investigated by light and scanning electron microscopy. The elongated olfactory organ is made up of 20 to 22 primary lamellae arranged on both sides of the narrow median raphe. Sensory and non-sensory regions are located separately on each lamella. The sensory epithelium occupies the upper apical broad half and extreme basal part of t...
متن کاملComparative morphology of the avian cerebellum: II. Size of folia.
Despite the highly conserved circuitry of the cerebellum, its overall shape varies significantly among and within vertebrate classes. In birds, one of the most prominent differences among orders is the relative size of the cerebellar folia. The enlargement/reduction of individual folia is thought to relate to specific behavioral differences among taxa, but this has not been adequately tested. H...
متن کاملComparative morphology of rodent vestibular periphery. II. Cristae ampullares.
We made flattened neuroepithelial preparations of horizontal and vertical (anterior and posterior) cristae from mouse, rat, gerbil, guinea pig, chinchilla, and tree squirrel. Calretinin immunohistochemistry was used to label the calyx class of afferents. Because these afferents are restricted to the central zone of the crista, their distribution allowed us to delineate this zone. In addition to...
